Ugh I was going to stay out of this, but I can't resist making one comment:

Speaking a different language with a stranger and speaking it with someone you know is very different. With a friend or husband, you'll know what speech style to expect. You're used to their pronunciation. Her husband will probably also know what level she's at, and alter his English to it, subconsciously even.

I'm proud she has the guts to take on English interviews. Japanese and English are nothing alike. Aside from a few loanwords, there's no vocabulary to build on. And the grammar is completely different. Comparing it to English and German (or any other European language) is unfair.
